drm/amdgpu: temporarily disable broken Clang builds due to blown stack-frame

2022-12-08T10:23:58+00:00

commit 6f6cb1714365a07dbc66851879538df9f6969288 upstream. Patch series "Fix a bunch of allmodconfig errors", v2. Since b339ec9c229aa ("kbuild: Only default to -Werror if COMPILE_TEST") WERROR now defaults to COMPILE_TEST meaning that it's enabled for allmodconfig builds. This leads to some interesting build failures when using Clang, each resolved in this set. With this set applied, I am able to obtain a successful allmodconfig Arm build. This patch (of 2): calculate_bandwidth() is presently broken on all !(X86_64 || SPARC64 || ARM64) architectures built with Clang (all released versions), whereby the stack frame gets blown up to well over 5k. This would cause an immediate kernel panic on most architectures. We'll revert this when the following bug report has been resolved: https://github.com/llvm/llvm-project/issues/41896.

drm/amdgpu/display: drop DCN support for aarch64

2021-01-23T15:03:58+00:00

commit c241ed2f0ea549c18cff62a3708b43846b84dae3 upstream. From Ard: "Simply disabling -mgeneral-regs-only left and right is risky, given that the standard AArch64 ABI permits the use of FP/SIMD registers anywhere, and GCC is known to use SIMD registers for spilling, and may invent other uses of the FP/SIMD register file that have nothing to do with the floating point code in question. Note that putting kernel_neon_begin() and kernel_neon_end() around the code that does use FP is not sufficient here, the problem is in all the other code that may be emitted with references to SIMD registers in it. So the only way to do this properly is to put all floating point code in a separate compilation unit, and only compile that unit with -mgeneral-regs-only." Disable support until the code can be properly refactored to support this properly on aarch64.

drm/amd/display: Clean up debug macros

2020-10-26T21:19:30+00:00

This patch simplifies the ASSERT*() and BREAK_TO_DEBUGGER() macros: - Move the dependency check of CONFIG_KGDB into Kconfig - Unify the kgdb_breakpoint() call - Drop the non-existing CONFIG_HAVE_KGDB Also align the behavior of ASSERT() macro in both cases with and without CONFIG_DEBUG_KERNEL_DC.

drm/amd/display: add DCN support for aarch64

2020-08-10T21:26:53+00:00

This adds ARM64 support into the DCN. This mainly enables support for Navi graphics cards. The dcn10 changes haven't been tested, since I don't have the relevant hardware available, but there is no way to conditionally disable them, so I've done them anyway.

amdgpu: Enable initial DCN support on POWER

2019-12-18T21:09:05+00:00

DCN requires floating point support to operate. Add the appropriate x86/ppc64 guards and FPU / AltiVec / VSX context switches to DCN. Note that the current DC20 code doesn't contain all required FPU wrappers on x86 or POWER, so this patch is insufficient to fully enable DC20 on POWER. v2: s/X86_64/X86/g to retain previous behavior.
